Abstract
Description
The derived color space specified by x, y, and Y is known as the CIE xyY color space. To return to a three-dimensional representation, the X and Z tristimulus values may be calculated from the chromaticity values x and y and the Y tristimulus value as shown below in Expression B.
In the above Expression C, W=the mean value on the de Boer scale, E=the average level of illumination directed towards an observer's eye from the light source (lux), θmax=the glare angle between the observer's line of sight and the light source at a location where maximum illumination occurs (minutes), and La=the adaptation illuminance (cd/m2). A person of skill in the art will appreciate that additional formulas for computing a glare rating are intended to be included within the scope and spirit of the present invention.
